"Listen to the urn? Is it to listen to the enemy's situation when you are fighting? Yao Huan asked with interest.

Bai Hua was surprised: "The lady also knows? “

Yao Huan said in his heart, because I have seen you Northern Song Dynasty eavesdropping tools in the museum in my last life.

Of course, this can only be muttering in his stomach, for the dolls in front of him, Yao Huan found the words smoothly: "I am from Gyeongju, and there is the same Xizhou where General Liu is located, and it is often necessary to guard against the attacks of the Western Xia people, and we know a little about this kind of listening urn." By burying it in the ground, you can hear the distance of the offenders from the city, the direction of the cavalry, and whether they will pretend to withdraw and actually dig tunnels. ”

It turned out that Yao Niangzi was also from the state and county of the Fifth Road of the Western Army.

Hearing her say this, the three children psychologically moved closer to Yao Huan.

"Yao Niangzi, my cousin Yuming was born without seeing, but General Liu said that the army will deliberately recruit blind soldiers, because they have very smart ears and are more handy with listening urns. Xihe Road still retains the military status of my father and uncle, and in a few years we are all going back to Xizhou to fight the Xixia people, so Cousin Yuming will start practicing using the listening urn now. ”

Bai Hua paused for a moment, and added: "But I don't want others to know, it's too annoying to ask questions, so we'll practice by ourselves." ”

Yao Huan was surprised, looked at the exposed eaves on the other side of the wall, and asked, "Next door, Futian Courtyard?" ”

Bai Hua said: "Yes, it seems that there are people in Futian Courtyard today who have come to send the New Year's gift of the Winter Solstice Festival, behind this wall, is the food cellar of Futian Courtyard, and the items are just being counted." ”

Yuming, a blind boy who looked a little shy in temperament, also took his cousin's words at this time and added: "The lady in charge of the courtyard also praised the sticky rice for being clean and sand-free. ”

Yao Huan was surprised, he could hear it so clearly? It's really a wall.

Before Shen Kuo's "Dream Creek Writings" was lent to Shao Qing, Yao Huan flipped through a few articles that he could understand.

She remembered that there was a kind of eavesdropping tool called "Yafu", which meant that when the army was marching and fighting, the soldiers would use hollow quivers made of cowhide as pillows, so that when they slept at night, they could hear the movement of the enemy troops several miles away.

But she didn't expect that listening to the urn was more powerful than Yafu.

"I'll hear it too."

Yao Huan put his right ear on the hollow pottery handle, and covered his left ear with his hand to avoid the noise of arrows in the distant yard.

Sure enough, there was a radio with a very low volume in the urn, playing the movement of the Futian Courtyard warehouse next door.

The sound of footsteps on the ground?

The sound of the grain bag dragging and pulling?

Someone shouted, "How can you be lucky to come here, pull it to the firewood house."

She straightened up?

Staring at the high courtyard wall to tell the difference?

But I could only hear the crows chirping on the bare elm tree over there in Futian Temple.

The contrast is so obvious.

Yao Huan found it very interesting.

She crouched down again?

Keep listening.

There was a creak of climbing a wooden ladder.

Suddenly, a woman's voice said, "The concubine is about to give birth?"

The official family will not pursue Xuanren at this time. Is it best for the concubine to give birth to a prince smoothly?

It only makes sense when we come to do this next year. ”

Someone replied to her: "The slave understands, the queen is in front, and Xuanren is in the back." ”

These two clear and terrifying sentences?

scared Yao Huan a lot.

The words of two women?

It's so close!

Yao Huan's ears seemed to be burned by the handle of the listening urn, and she almost shrank back.

I can hear the various movements of the things just now because they are very loud and noisy.

But at this moment, this sudden human voice is not a call sign?

It's as vivid as coming through a curtain.

No matter how powerful the listening urn is, it is not a modern bugging device after all.

Yao Huan turned back?

Seeing that the attention of the three children was attracted by the crows that made their nests on the branches of the tree.

She tried to steady herself, and her mind raced like electricity.

Barn?

Barn...... She seemed to understand a little, the creak of the wooden ladder?

The words that suddenly came from far to near......

Cellar.

Where do they bury their listening urns?

Not so much the warehouse across Fukuda-in?

Rather, it is more likely to be closer to a cellar-like space.

Yao Huan continued to crouch into the cave and put his ear on the clay tube.

"I often enter the palace this time, and Fuqing likes me."

"It's good to like it, when she is about to die, you are as anxious as her mother, so it makes sense. It's not easy to get out of the palace, so I'm leaving. ”

After listening to the urn, the voices of the two women could not tell whether they were old or young, and they seemed to have undergone voice change processing.

Ping...... Table tennis......!

Suddenly, there were several loud bangs.

In the yard, Liu Xi took the dolls and began to set off firecrackers.

It turns out that the winter solstice festival of the Song people also has to set off firecrackers?

Yao Huan, who was interrupted by the sound of firecrackers, couldn't hear any movement when he got closer to the listening urn.

"Brother, cousin, I want to see the explosion."

The little girl raised her head, looked at the firecrackers that exploded in the air, and turned around to pull Yuming.

Although Yuming's eyes were closed, his face was clearly excited, and he was led by his cousin to the other end of the vegetable field.

Yao Huan got up and said to Bai Hua: "Let's go, let's go and see General Liu release the battle." ”

Unlike Ah Crossbow and Yuming, Bai Hua's expression was clearly wistful.

Yao Huan felt that the sudden sound of firecrackers was like a thunderous external force, which made her wake up from the terrifying and strange conversation she had just heard.

It also made her observe the different colors on the face of the half-grown child.

Judging from his previous enthusiastic narration, he should have admired Liu Xi. But apart from his cousin and sister, he seems reluctant to join other peers in the orphanage.

crackling, another series of "continuous sounds", more lively than the few "two kicks" just now.

Bai Hua squatted down, quickly buried the urn with soil, and then piled up the broken stones.

Yao Huan patiently waited for him to finish this, patted him on the shoulder, and said to him: "Listening to the urn is more fun than firecrackers, thank you for inviting me to come and see." I don't tell anyone else to know. ”

Bai Hua raised his head, and a faint innocent smile appeared between his eyebrows.

The four of them came to the periphery of the courtyard, and there were a few centipede-like explosions on the snow.

Yao Huan saw it with his own eyes, and only then did he understand why in the Song Dynasty, firecrackers were renamed as firecrackers.

Due to the development of gunpowder technology, the Song people have been able to make explosives with paper rolls of gunpowder, so there is no need to throw bamboo chips into the fire to make a sound like the Tang people did in the New Year's Festival.

General Liu Xi and Liu happily handed a piece of incense to Meituan, Xiao Yue'er had already covered her ears, but Meituan walked to the lead of the explosion with a dashing look, and quickly jumped back after lighting it.

In the crackling explosion, Liu Xi gave a thumbs up to Meituan.

A boy who looked about the same age as Bai Hua, after the explosion burned out, was about to order another string, but suddenly ran over and gestured to Meituan to ask her to order.

Yao Huan was squinting at this situation, and suddenly heard Bai Hua beside him say coldly: "Sycophant." ”

Yao Huan turned his head sideways, and when he saw Bai Hua's gaze, it should also fall on the boy's body.

She seemed to have guessed a little bit of Bai Hua's thoughts.

Where there are people, there are rivers and lakes, and half-grown children have rivers and lakes, and the bloody wind and rain may not be able to talk about it, but the situation that they don't like each other may not be less.

The boy doll looks like the "leading brother" of the orphanage, and in front of people, the building is full of red sleeves and beckons.

Maybe Bai Hua didn't deal with him, so he and Yuming didn't want to reveal it to other children.

Yao Huan thought of listening to the urn, and memorized the three sentences he had just heard.

Xuanren, enter the palace, Fuqing, leave the palace......
